20V Max Grease Gun, Bare Tool

Overview

The DeWalt 20V Max Grease Gun (DCGG581B) is designed for professional lubrication applications requiring high-pressure output across automotive, heavy equipment, and general maintenance environments. Sold as a bare tool — battery and charger sold separately.

Technical Features

• 10,000 Max PSI output — delivers sufficient pressure to clear clogged grease fittings without manual effort, maintaining lubrication schedules on demanding equipment.
• 2-Speed operation — allows the operator to select between high-volume and controlled-flow modes, making the tool suitable for both bulk lubrication tasks and precision applications.
• Variable speed trigger — provides real-time control over grease flow rate, reducing waste and preventing over-greasing on sensitive components.
• Up to 9 oz. per minute dispense rate — supports high-flow applications where throughput and cycle time are critical.
• Up to 7 grease tubes per charge — reduces downtime associated with reloading or recharging during extended maintenance runs.
• 47-inch reinforced flexible hose — enables access to fittings in confined or obstructed spaces without repositioning the tool body, improving jobsite efficiency.
• 20V Max cordless platform — eliminates pneumatic line dependency, allowing use in locations without compressed air infrastructure.

Applications

• Lubrication of zerk fittings on heavy construction and agricultural equipment
• Automotive chassis and undercarriage maintenance
• Fleet maintenance operations requiring repeated greasing cycles
• High-flow greasing tasks where dispensing speed and volume are priorities
• Servicing fittings in hard-to-reach or confined locations using the extended flexible hose
